The range of RF products is usually communicated as a single number which refers to the longest line of sight (LOS) distance that holds a stable link. This number is usually measured in a large, open place far from any obstacles or interferers. For the CC8520 the LOS range is 35m+ and 130m+ when adding the range extender CC2590 in the RF chain. The CC8520 will rarely operate under such conditions, but more likely in difficult RF environments including reflectors like walls and floors. In order to present more practical range information than what lies in the LOS range of the CC8520, a real world range test have been conducted where the performance in several test positions inside an office environment is presented.
